Params

• On JavaScript :

// Example
const bbs = require('blum-blum-shub');
const BBS = new bbs(9, 15, 7);

let i = 0;

while(i < 6) {
	// Get the next random number
	console.log(BBS.randomNumber());
	
	// Get the next random bit
	console.log(BBS.randomBit());
	
	i++;
}

• On CoffeeScript :

# Example
bbs = require('blum-blum-shub')
BBS = new bbs(9, 15, 7)

 i = 0

while i < 6
	# Get the next random number
	console.log BBS.randomNumber()
	
	# Get the next random bit
	console.log BBS.randomBit()
	
	i++

...

Benchmark

• randomNumber x 10,425,712 ops/sec ±0.86% (89 runs sampled)
• randomBit x 10,280,317 ops/sec ±0.92% (90 runs sampled)
• Fastest is randomNumber

Fact

Blum Blum Shub (BBS) is an algorithm capable of producing pseudo-random numbers. It was proposed in 1986 by Lenore Blum, Manuel Blum and Michael Shub1, hence its name.
